I am trying to replace the genuine Subaru satellite radio module in my 2013 Subaru Legacy 26i Premium. It was installed by the dealer who sold me the car used. It has an antenna mounted on the windshield. (the car's manual confirms that where the factory antenna would be) I have tried everything I can think of to improve the reception, which drops out frequently. Remedies attempted included having Sirius refresh the signal many times, moving the position of the antenna (magnetic rooftop antennas are incompatible) and of course having another Subaru dealer diagnose the module (they can't find a problem, though we took a ride and they heard the dropouts) . This module part is discontinued. It is H621SAJ000. A supplier of Subaru parts says a new part H621SAJ100 supercedes it. Here's the question: Does anyone have any experience with this switching of parts? Is it truly compatible, and is it a real upgrade? Or any other suggestions? thanks.

factory equipment with my 2013 Legacy, bought used last year, is an antenna for the factory satellite radio mounted on the windshield. The 2013 Subaru manual warns that if you are driving North near the coast it will not work well. The manual is correct in my experience. In fact, reception fails a lot, unlike my previous, older, cheaper car with a factory sharkfin (external) satellite antenna. Anyone else have this problem with their Subaru? Have you found any solutions?
